Puzzlement

Messing around on the desk. Not sure what is going on. Note that this is from a pre-production unit that has been a little flaky in the past. How can the calculated velocity be zero with such wild swings in indicated altitude?

AirWalker flight 13 (from Android)

In the light. Q-Jet C12-6. Note that this was uploaded many days after the flight so the automatic weather info here does not match the actual flight data. Data posted shortly after the actual flight here: https://flightsketch.com/flights/521/

Nova Payloader(4) flight 19

Chinese Quest B6-4 and model in better condition. Compare with Nova Payloader(2) Flight 101 just below. Another reluctant parachute on this chilly afternoon. See Larry Kennedy's Super Neon XL flight picture below to get an idea of what the day looked like :-).

Nova Payloader(2) flight 102

Estes B6-4. Parachute was reluctant to open, but finally did, which is why descent part of the curve looks as if I had a Chute Release. Overall profile was actually quite pretty for what will probably will have been the retirement flight of this model.

Checkmate flight 36

First flight after rebuild from failed second stage ignition last Saturday (see https://flightsketch.com/flights/543/). A10-0T / A3-4T. Steamer did not deploy. FS Mini was unresponsive when reached. Had to pull cell out and put it back in to wake it up. But data look plausible for the flight.

Super Neon XL - E18-5W

Black Brant B6-4

Cold and overcast November day. Last launch of the year

Nexus flight 21

C12-6 Q-Jet. Very nice flight all around.

Boosted Bertha flight 8

B6-0 / A8-3. This combination would make a good schoolyard demo (at least in low wind).
